Stability study of open mine slopes at pit 22 GN PT Kitadin Site Embalut, Kutai Kartanegara Regency, East Kalimantan Province

The stability of slope, both on the slope work and final is a very important aspect stability, in open pit mining activities. inconsistency slopes will result collapse rocks around excavation site. This happens because condition rock when it has not been excavated generally balanced. However, due to discontinuous patterns that occur other than naturally also activities such as excavation, blasting others, cause reduction retaining force results equilibrium tends shift Study highwall at PIT 22 GN PT Kitadin Site Embalut, Kutai Kartanegara Regency, East Kalimantan Province was carried out with aim know characteristics, calculate geometry stable safety factors, recognize type landslide using bishop method. modeling consist several heights slopes, well angles formed.
